                 ],
        "version" => "2.3"
    }

I want to use ruby code to handle every PMMOResult block, the related ruby code such like this:

 if "_xmlparsefailure" not in [tags]{
                ruby { code => "

                                pmMeasInfo = event.get(['parsed']['PMSetup'][0]['PMMOResult'])
                                pmMeasInfo.each do |pr|

                                     ... ...

                               end
                               ... ...

                             "}

Then this sentence "pmMeasInfo = event.get(['parsed']['PMSetup'][0]['PMMOResult'])" make the ruby exception result.

[2018-05-14T19:08:18,912][ERROR][logstash.filters.ruby    ] Ruby exception occurred: can't convert String into Integer

Experts, would you please help me check this issue? How can I get every data from "PMMOResult", then put them into an array/hash_array?

Thank you.

@magnusbaeck expert, can you help check it? Thank you.

For a LS nested field reference, you need to put the all the brackets in one continuous string.
pmMeasInfo = event.get("[parsed][PMSetup][0][PMMOResult]")
Single quotes are OK too - I used double quotes here as they are easier to see.

Guyboertje, great thanks a lot for your answer, I have modified it to
pmMeasInfo = event.get("[parsed][PMSetup][0][PMMOResult]")
Then it can work without rubyexception.

It block me a long time, thanks agian.
